of Government depository, university, or other libraries.

Limitation on Free Distribution of Publications

In the interest of economy, the U.S. Department of Agriculture is limiting the number of publications that
can be distributed free to 1,000 copies. Accordingly, all publications shown as newly available in our Publications List will be sent out on a first-come, first-served basis, and one copy to a "customer." All these publications will be available for sale by the National Technical Information Service (NTIS), U.S. Department of Commerce, Springfield, Virginia, in either paper copy or microfiche. If your request is received after our supply
is exhausted, we will furnish you information from NTIS on how to order copies and their cost.
